Prison violence: Isolate criminal gang members

Just as gardaí face danger unarmed every day, so, too, do prison officers.  

With little more than bare hands and raw courage, they have to deal with violent criminals, and some of the prison officers suffer injury as a result.

The situation is particularly acute when it comes to inmates who are members of criminal gangs, some of whom appear to be able to direct their nefarious operations from inside their prison cells.
